OBJECTIVE: To explore the relationship between subjective mood, folate status and homocysteine in healthy individuals. DESIGN: Subjective mood assessments were completed twice daily over the course of one week using the Positive and Negative Affect Scale (PANAS). The PANAS is a validated scale which considers mood state on two distinct continua, one reflecting positive mood and the other negative mood, each requiring response to 10 adjectives on a Likert scale. A blood sample was taken on one occasion at the start of the week during which subjective mood was assessed and analysed for red-blood-cell (RBC) folate, serum folate and plasma homocysteine concentrations. SUBJECTS: Male volunteers aged 19-47 years (n = 58) were recruited from local industries. RESULTS: High concentrations of RBC folate were associated with less variability (lower standard deviation) in negative mood (P = 0.023). Subjective mood, however, was not related to serum folate or homocysteine. CONCLUSIONS: This study appears to be the first to uncover an association between long-term folate status and subjective mood (employing the PANAS) in healthy males. More research is needed to further explore the relationship between nutritional status and mood. 相似文献

Panel data from a survey of small-scale farmers in the North Carolina Piedmont are used to investigate the survival of black smallholders. Results of a multivariate analysis show that owning tobacco quota and having high gross farm income, high amounts of on-farm household labor and small household size increase the propensity to survive in agriculture. Over the five-year period studied, approximately 50 percent of the original respondents were no longer actively operating farms. These results point to the complex problems that policies designed to assist minority and small-scale farmers must address.Revised version of a paper presented at the annual meetings of the Rural Sociological Society, Norfolk, Virginia, August, 1990. This research received support from the North Carolina State University Title XII Strengthening Grant (AID/DSAN-XII-G-103) funded jointly by the U.S. Agency for International Development and the North Carolina Agricultural Research Service and conducted in collaboration with the North Carolina Agricultural Extension Service and the North Carolina A&T State University (Greensboro). Additional support was received from the North Carolina Agricultural Foundation. The opinions expressed are those of the authors. 相似文献

The case history, radiographic and scintigraphic findings of two horses with pelvic limb navicular bone fractures are presented. In both cases the fractures were of traumatic origin. One horse had a bilateral fracture of the navicular bone, distal border, the other horse had a fracture of the proximal articular border in one pelvic limb navicular bone. 相似文献

OBJECTIVE: To determine plasma and urine concentrations of retinol, retinyl esters, retinol-binding protein (RBP), and Tamm-Horsfall protein (THP) in dogs with chronic renal disease (CRD). ANIMALS: 17 dogs with naturally developing CRD and 21 healthy control dogs. PROCEDURE: A diagnosis of CRD was established on the basis of clinical signs, plasma concentrations of creatinine and urea, and results of urinalysis. Concentrations of retinol and retinyl esters were measured by use of reverse-phase high-performance liquid chromatography. Concentrations of RBP and THP were measured by use of sensitive ELISA systems. RESULTS: Dogs with CRD had higher plasma concentrations of retinol, which were not paralleled by differences in plasma concentrations of RBP. Calculated ratio of urinary total vitamin A (sum of concentrations of retinol and retinyl esters to creatinine concentration) and ratio of the concentration of urinary retinyl esters to creatinine concentration did not differ between groups. However, we detected a significantly higher retinol-to-creatinine ratio in the urine of dogs with CRD, which was paralleled by a higher urinary RBP-to-creatinine ratio. Thus, in dogs with CRD, the estimated fractional clearance of total vitamin A, retinol, and RBP was increased. Furthermore, dogs with CRD had a reduced urinary THP-to-creatinine ratio. CONCLUSIONS AND CLINICAL RELEVANCE: Results of this study documented that CRD affects the concentrations of retinol in plasma and urine of dogs. Analysis of the data indicates that measurement of urinary RBP and urinary THP concentrations provides valuable information that can be helpful in follow-up monitoring of dogs with CRD. 相似文献

Melarsomine dihydrochloride is highly effective against both sexes of adult and L5 Dirofilaria immitis. Common adverse reactions include injection site irritation and reluctance to move. Neurologic complications associated with i.m. injection of melarsomine dihydrochloride for treatment of heartworm disease in 3 dogs are described. Different degrees of neurologic complications have been identified; the pathophysiologic features are unknown. It is speculated that the compound migrates out of the injection site via fascial planes and causes an ascending inflammation along nerve roots. The resulting extradural cord compression secondary to extensive inflammation and necrosis of epidural fat could induce a variety of neurologic deficits. Alternatively, inappropriate injection technique may result in direct contact of melarsomine with neural tissue. A heightened awareness of proper injection technique might prevent the development of most neurologic complications. 相似文献

OBJECTIVE: To determine whether rocuronium, a reversible neuromuscular blocking agent, would provide safe, short-term immobilization to facilitate endotracheal intubation in turtles. DESIGN: Prospective study. ANIMALS: 30 healthy adult Gulf Coast box turtles. PROCEDURE: Turtles were given rocuronium, and responses were recorded every 3 minutes. Times to onset of effects, intubation, and recovery were recorded and analyzed for associations with dose and patient characteristics to determine an optimal dose range. Neostigmine and glycopyrrolate were given to augment recovery from neuromuscular blockade. RESULTS: Rocuronium administered at a dose of 0.25 to 0.5 mg/kg (0.11 to 0.23 mg/lb), IM, permitted intubation; lower doses were not effective. Mean +/- SD time to loss of the palpebral reflex was 6.4 +/- 4.0 minutes, and mean time to intubation was 9.2 +/- 6.4 minutes. Mean time to return of the palpebral reflex was 44 +/- 13.2 minutes, and mean time to walking was 55 +/- 16.6 minutes. Time to onset of effects was not associated with dose, but recovery times were prolonged with higher doses of rocuronium. Cardiac arrhythmias were observed in 13 (43%) turtles. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of rocuronium at a dose of 0.25 to 0.5 mg/kg is a safe and effective adjunct to general anesthesia in Gulf Coast box turtles. Because rocuronium does not provide any analgesic or sedative effects, the duration of neuromuscular blockade without anesthesia should be minimized to avoid undue distress. 相似文献

A 2-week-old Morgan filly examined because of lameness of 5 days' duration was found, on the basis of clinical and radiographic findings, to have septic physitis of the distal end of the radius. The foal was treated by means of intraosseous regional perfusion with penicillin and amikacin and systemic administration of antimicrobials. Intraosseous regional perfusion was performed 3 times. The foal was anesthetized for the first episode of intraosseous regional perfusion, but was only sedated for the subsequent 2 episodes. Antimicrobials were administered systemically for 22 days. Foals with septic physitis are typically considered to have a guarded to poor prognosis for recovery; however, this treatment regimen resulted in relatively fast and uncomplicated resolution of the infection in this foal. 相似文献

Eight cats with locally advanced, oral squamous cell carcinoma (SCC) were treated with a combination of gemcitabine and palliative radiotherapy. Low-dose gemcitabine was administered twice weekly (25 mg/m2) in conjunction with megavoltage radiation in 6 Gray (Gy) fractions for a total dose of 36 Gy. Responses included two complete and four partial responses, and two cats had no response to therapy. Median duration of remission was 42.5 days (range, 11 to 85 days). Median survival time was 111.5 days (range, 11 to 234 days). This data suggests that a combination of low-dose gemcitabine and palliative radiation therapy may be tolerable for cats with oral SCC and may cause a therapeutic benefit. 相似文献

Using a leaf disc transformation procedure andAgrobacterium- mediated gene transfer, transgenic apple and strawberry plants have been produced that carry a gene encoding a cowpea trypsin
inhibitor (CpTl). This gene is known to confer resistance to several lepidopteran and coleopteran insect pests. Scientific
and regulatory aspects of this type of work are discussed. 相似文献
